" FIXED AMMUNITION.

Specification of Letters Patent.

Patented May 1, 1996.

I 'Appliqafion filed July 27, 1905. Serial No. 271,521.

To all whomit may concern Be it known that I, OLIVER E. J. BRUBA- KER, a citizen of the United States, residin at Allegheny, in the county of Allegheny an State Penns lvania, have invented certain new and use Improvementsin Fixed Am- I munition, of which the following is a specifing direct access to the latter, thereb avoidtlion of the invention carrying asolid through perforations F.

ing overheating the projectile and e 'minating-danger of its premature explosion.

the accompanyin a longitudinal sectionaIview of my improved ammunition carrying a high-explosive projectile. Fig. 2 is a similar view of an ada tar ro ect- Fig. 3 is a sectional view of a sliotgunshell constructedin accordance with my in-" vention. v

Refe to the drawings, A designates the casing ors ell proper, B the base, and C the primer. Secured to and projecting inward from the base is the powder-tube-D, which is open adj acent base B, as indicated at D, for: communicating with the interior of casing A. In the high-explosive-projectile adaptation of Fig. 1 a head E is secured in the outer end of casin A, the head being, recessed and formed wit the inwardly-projecting airchamber F, open to the interior of cas A The. tubular orward projection E of the head is adapted to receive the rear end of. the high-ex losive:

- projectile G.. Thus it will be seen t at an apertures {MI-$58.06 Hof considerable extent is inter: pose between chamber F and the powdertube D and that the 'rear'portion of that s ace surrounds said tube, .When the power or other explosive in tube D is fired, the exploded g)as,es issue into space H through ,and in comb" with the air gain shown, 1nwhich the charge 0 shot may be drawings, Figure 1 is in said spacekperfect combustion is had, all products being consumed,

thereby obtaining the maximum eiiiciency of the exploding charge. At the same time the air in space H so cushions the explosion that there is practically no recoil, this cush- 6o ioning being effected Without detracting from the propelling force of the explosion exerted upon theprojectile. The rear end of projectile G is protected from direct contact with the explodin charge by chamber F, into 6 which the explo 'ng gases can pass only through apertures F, the air within chamber F preventing the projectile from becoming overheated and exploding prematurely.

In the adaptation shownin Fig. 2, wherein a solid projectile J is substituted for a highexplosive projectile G, the air-chamber F is omitted, as with ammunition of this character 1 no damage results if the projectile or its rear end becomes heated. Otherwise the construction and operation are as above described. In Fig. 3 an ordinary cartridge or shell K is confined in the forward end L of the shell in any suitable manner, the powder-tube D being arranged in its rear end exactly as above described, with the air-space I-I intervenin between the powder-tube and the shot an o crating to cushion or prevent recoil and at t e same time causing perfect combustion of 8 5- the exploding charge.

a 1 From the foregoing it will be understood that the invention is adapted for any and all kinds of fixed ammunition, regardless of whether the projectile is Wholly or artially 9o within the shell proper or casing an regardless of whether the projectile carries an explosive or not.

" I claim- 1. The combination with a shell for fixed: 5

ammunition, of a powder-container therein and communicating therewith at its rear end only.

2. The combination with a shell for fixed ammunition, of 'a powder-container therein '1 oo.

sustained by the shell-base, the container commumcating with the shell only at its rear end.

' 3. The combination with a shell for fixed ammunition, of a powder-container therein sustained wholly by the shell-base. 4. The combination of. a casing, a powdertube projecting into the casing from the base, a projectile, and an air-space separating the projectile and tube and surrounding ter.

5. The combination of a casing, an explothe latno sive in the rear end thereof, a projectile, and an air-chamber separating the projectile from the explosive, said chamber being open to admit the exploding gases.

6. The combination of a casing, a powder container therein, a projectile, an air-chamber at the rear of the projectile and open to the casing to admit the exploding gases, the

casin having an air-space between said aircham er and the powder-container. IO In testimony whereof I aflix my signature in presence of two witnesses.
